Impinduka ya titanium dioxide yo mu rwego rwo hejuru yafunguwe

Isoko rya titanium dioxide rishyushye mu myaka myinshi ryakomeje gukonja kuva mu gice cya kabiri cy'umwaka ushize, kandi igiciro cyagiye kigabanuka buhoro buhoro. Kugeza ubu, ibiciro bitandukanye bya titanium dioxide byaragabanutseho ibirenga 20%. Ariko, nk'igicuruzwa cyo mu rwego rwo hejuru mu nganda za titanium dioxide, uburyo bwa chlorine bwa titanium dioxide buracyari bukomeye.

“Chlorination titanium dioxide ni nacyo gitera imbere mu iterambere ry’inganda za titanium dioxide mu Bushinwa. Mu isoko, iterambere mu ikoranabuhanga, inyungu zikomeye n’izindi, mu myaka ya vuba aha, ubushobozi bwo gukora titanium dioxide ya chloride mu gihugu bwariyongereye cyane, cyane cyane umusaruro munini w’ibikoresho bya titanium dioxide bya Longbai Group byagabanyije ibintu ku buryo ibicuruzwa byo mu rwego rwo hejuru bigengwa n’ibihugu by’amahanga, kandi impinduka ikomeye ya titanium dioxide mu gihugu yari iri mu nzira.” Ibi byavuzwe na Shao Huiwen, umusesenguzi mukuru w’isoko.

Ubushobozi bwo gukora chlorine bukomeje kwiyongera

“Mu myaka itanu ishize, ibicuruzwa bya titanium dioxide bya chlorine byari bifite 3.6% gusa by’umusaruro wo mu gihugu, kandi imiterere y’inganda yari idahwitse cyane.” He Benliu yagize ati: “Imyaka irenga 90% by’ikoreshwa rya titanium dioxide mu gihugu rishingiye ku bitumizwa mu mahanga, igiciro cyabyo gihenze cyane kurusha titanium dioxide rusange yo mu gihugu. Ibicuruzwa bigezweho bifite urwego runini rwo kwishingikiriza hanze, kandi nta mbaraga z’inganda zikoresha titanium dioxide ya chlorine, ari nabyo imbogamizi mu guhindura no kuvugurura inganda za titanium dioxide mu Bushinwa.”

Imibare ya gasutamo igaragaza ko mu gihembwe cya mbere cya 2023, ubwikorezi bwa titanium dioxide mu Bushinwa bwungutse toni zigera ku 13.200, bwagabanutseho 64.25% ugereranyije n'umwaka; ingano y'ibyoherezwa mu mahanga yose yari toni zigera ku 437.100, ubwiyongere bwa 12.65%. Nk'uko andi makuru abigaragaza, ubushobozi bwo gukora titanium dioxide mu Bushinwa mu 2022 ni toni miliyoni 4.7, ibicuruzwa biva mu mahanga byagabanutseho 43% ugereranyije n'umwaka wa 2017, naho ibyoherezwa mu mahanga byazamutseho 290% ugereranyije n'umwaka wa 2012. “Mu myaka ya vuba aha, ubwikorezi bwa titanium dioxide mu gihugu bwaragabanutse kandi ingano y'ibyoherezwa mu mahanga yariyongereye, kuko kwiyongera kwihuse k'ubushobozi bwo gukora chloride titanium dioxide mu bigo bikomeye byo mu gihugu byagabanyije cyane kwishingikiriza ku bicuruzwa byo mu rwego rwo hejuru bitumizwa mu mahanga.” Umuyobozi w'ikigo gitunganya irangi mu gihugu yagize ati.

Nk’uko He Benliu abivuga, inzira nyamukuru ya titaniyumu igabanyijemo uburyo bwa aside sulfuriki, uburyo bwa chlorination n’uburyo bwa aside hydrochloric, aho inzira ya chlorination ari ngufi, yoroshye kongera ubushobozi bwo gukora, urwego rwo hejuru rw’imikorere ihoraho, ikoreshwa ry’ingufu nke, imyuka mike “itatu” ihumanya, ishobora kubona ibicuruzwa byiza, ni yo nzira nyamukuru ikoreshwa mu nganda za titaniyumu. Igipimo cy’ubushobozi bwo gukora titaniyumu ya chlorination na aside sulfuriki ya titaniyumu ni hafi 6:4, mu Burayi na Leta Zunze Ubumwe za Amerika, igipimo cya chlorination kiri hejuru, igipimo cy’Ubushinwa cyazamutse kigera kuri 3:7, itegurwa ry’ibura ry’ibikoresho bya titaniyumu ya chlorination rizakomeza kunozwa.

Kunywa chlorine biri mu cyiciro gishishikarijwe

“Katalogi y’amabwiriza yo kuvugurura imiterere y’inganda” yatanzwe na Komisiyo y’Igihugu Ishinzwe Iterambere n’Ivugurura yagaragaje ko ikorwa rya dioxyde ya titanium ifite chlorine mu cyiciro cyatewe inkunga, mu gihe hagabanywa uburyo bushya bwo kudakora hamwe kwa aside sulfurike titanium dioxyde, bwabaye amahirwe yo guhindura no kuzamura inganda za titanium dioxyde, kuva icyo gihe inganda zo mu gihugu za titanium dioxyde zatangiye kongera ubushakashatsi n’iterambere n’ishoramari mu ikoranabuhanga ryo gukora dioxyde ya titanium ifite chlorine.

Nyuma y’imyaka myinshi y’ubushakashatsi bwa tekiniki, kugira ngo bikemure ibibazo byinshi muri dioxyde ya titanium ya chloride, Longbai Group yateguye urutonde rw’ibicuruzwa byinshi bya dioxyde ya titanium ya chloride yo mu rwego rwo hejuru, umusaruro rusange wageze ku rwego mpuzamahanga rwo hejuru, umusaruro umwe wageze ku rwego mpuzamahanga rwo hejuru. Turi aba mbere bagaragaje ubuhanga bushya mu bucuruzi bunini bwa titanium dioxyde ishyushye ya chlorine, kandi ikoranabuhanga ryagaragaje ko ikoranabuhanga rya titanium dioxyde ya chlorine ari ryiza kandi rirengera ibidukikije, uburyo bwaryo bwo kugabanya imyanda kurusha aside sulfure bugabanya ibirenze 90%, kuzigama ingufu kugeza kuri 30%, kuzigama amazi kugeza kuri 50%, inyungu ku bidukikije ni ingenzi cyane, kandi umusaruro w’ibicuruzwa uhuye n’ibipimo by’ibitumizwa mu mahanga. Mu gihe gito, ubushobozi bw’abanyamahanga ku isoko ryo mu rwego rwo hejuru bwarangiritse, kandi ibicuruzwa byemejwe n’isoko.

Nyuma y’umusaruro w’imishinga mishya ya titanium dioxide ikomoka muri chlorine mu gihugu, ubushobozi bwayo bwo kuyikora bwageze kuri toni miliyoni 1.08 mu 2022, bivuze ko ubushobozi bwose bwo kuyikora mu gihugu bwazamutse kuva kuri 3.6% mu myaka itanu ishize bugera kuri 22%, bigabanya cyane uburyo ikoreshwa n’ingufu za titanium dioxide ikomoka kuri chlorine, kandi inyungu ku isoko yatangiye kugaragara.

Abahanga mu nganda bemeza ko hashingiwe ku iterambere ry’ikoreshwa rya dioxyde ya titanium yo mu rwego rwo hejuru, ndetse n’imiterere n’uko inganda zo mu gihugu zimeze ubu, ihinduka rya dioxyde ya titanium yo mu rwego rwo hejuru mu Bushinwa ryatangiye guhungabanya umutekano. Bivugwa ko inzego za leta n’inganda bireba bigomba kongera kwita ku igenamigambi ry’imishinga ya chlorine, kandi ibigo na byo bigomba kwibasirwa, kureka ishoramari ry’imishinga no gutegura ibikorwa bisubira inyuma n’ibicuruzwa bisubira inyuma, no kwibanda ku iterambere no gukoresha ibicuruzwa bisubira inyuma kugira ngo hirindwe ibyago byo kubura ibicuruzwa byinshi birengeje urugero.
